A discussion of the myth of Lot & his daughters in my current GD thread got me wondering this. I don’t drink very much and never have, and I’ve never had sex with drunk, or even buzzed. I’ve always assumed that the guy’s performance under such circumstances would be significantly less than impressive, but in fact I have no personal experience to back that up.
Reduce my ignorance.
Unfullfilling.
They call it “whiskey dick” for good reason.
My personal experience:
Even very mildly drunk, it’s disappointing. The intoxication gets between me and the experience.
And since I don’t handle alcohol very well, when I’m more than mildly buzzed I couldn’t stick a carrot in a washtub.
(Thanks and a tip of the hat to Ken Kesey for the carrot metaphor.)
.
It’s better, to a point…then unfulfilling…then impossible. All relative to how much alcohol you have when starting the deed. 1 to 2 drinks will have me lasting longer (which is good), 3-4 drinks will numb things too much (which is bad)…5+ drinks will make the beastie unable to perform.
I submit that it’s no fun unless both partners are drunk. At least then you can have a good laugh. 
Drunk partners are usually enthusiastic but clumsy.
Endless, tiresome, boring.
A large part of the pleasure for me is the interaction. When he was drunk, he was an automaton. I could just as well have hooked myself up to a modified pile-driver.
I agree with this. When I’m drunk I get horny (rarely do I get too drunk to perform these days) and I get real enthusiastic, but I’m sure I’m a clumsy ox. It’s still fun and I enjoy having drunken sex then passing out. It’s definitely not better than sober sex, but it’s fun and fulfilling enough for me at the time. I have a girlfriend, though, so I can get laid virtually whenever I want, so lacking a little fulfillment during one row isn’t much of a drawback as I can always just come back for seconds later
Increases the desire, robs the performance. I have fond memories of drunk sex, but that’s usually due to the circumstances surrounding my inebriation. It’s usually with an enthusiastic partner that’s new (to me) so that’s always fun. Sober sex is usually with a girlfriend and thus isn’t as “fun”.
I have yet to encounter a time that alcohol robbed my ability to perform when I was otherwise conscious and willing. The alcohol makes me pass out, but I’ve certainly never been standing there going “come on, little buddy, pleeeeeease do you thing!”
Boring, after a point. I’ve never had a problem getting an erection, but orgasm has been a problem a number of times, and after a while, I might as well be doing push-ups or some other repetitive exercise.
Lady here.
It depends on how drunk he is and how drunk I am.
Both a little tipsy, fun, even though ungraceful.
He’s more than a little tipsy: boring.
He’s really drunk: non-functional, not even fun to have him try anything, he sleeps on the sofa.
I’m a little more than tipsy: if he’s able to perform, drunken, not really great sex.
I’m really drunk and he still can: not a lot of fun, more like get it over with.
Not great. Anything more than a buzz and it’ll seem like a good (blurry) idea at the time when we begin but end in slight nausea and no orgasm. It just doesn’t send blood to the right places. Other substances, on the other hand…
ETA: I see you were asking about having sex with a drunk guy. Not sure, since I’ve never been sober with a drunk partner. It certainly didn’t enhance the experience.
Ist’ awsoeme.
What are you doing on the computer!? Get back in the [del]dungeon[/del] bedroom!
But seriously, like others have said, it depends on the number of drinks. 1 to 3 makes for a longer lasting and generally better evening. 4 to 5 makes it very frustrating and sometimes incurs performance issues. More than 5 makes the evening a likely flop.
When really drunk, it’s like trying to play snooker with a rope.
Boring. It takes the guy a really long to get it up, and they’re so numb that they can’t orgasm, so they just hang out banging away while you get sore and annoyed. I prefer drunk handsy making out until all parties are in fit state to perform.
Echoing some of the others - a couple drinks is fine and maybe even a plus, more than that and it starts getting awkward, eventually you get to the point where it’s too numb to be satisfying for anyone.
“It makes a man stand to, and not stand to”
--*Macbeth* Act II, Scene 3. Macbeth's Porter, talking about the effects of drink.
Pretty much what the other guys have said. I don’t have a problem getting erect and the orgasm may never come but as long as I can get her off then mission accomplished. Night time.
HOWEVER, I’m horny as a m’fer the next morning. Hangover sex is the bomb! Seems all the nuerons are firing in just the right places and things get more sensitive. I’ve heard other guys and gals say the same thing. If the lady and I tie one on the night before it’s likely we can stay in bed all day and just play around. Good times.
